This project gives the ability to track where Soldiers are at any given moment. Search and rescue efforts become minimized in time and resources. Additionally, with alert feature Soldiers will be able to communicate their distress with GPS coordinate information. Location tracking has been of great importance since World War II, when military planners realized its usefulness for targeting, fleet management, positioning, and navigation. I have designed a reliable, energy efficient remote soldier monitoring system. It is able to send parameters of soldier in real time. It enables the army station to monitor soldier s parameters (temp, heartbeat, location) in real time. Here the parameters of soldiers are measured continuously (temp, heartbeat, location) and wirelessly transmitted using GSM. Keywords ARM, GSM, GPS, Sensors, LCD. I. INTRODUCTION Nowadays Defence services are rapidly growing towards new innovation with advance implementation. Soldier s health is more important because they are the defenders who protect our country [].The system is composed of two parts, which are portable remote soldier unit and the monitoring centre. The portable remote soldier unit consists of Advanced RISC Machines (ARM) with the embedded operating system, GPS and a GSM, temperature sensor and heart bit arte sensor []. II. A COMPLETE SYSTEM The proposed work of this project is to develop a system that can be supplemented with real-time wireless monitoring systems which are designed and implemented through GPS network and are able to record and transmit bio-signals of soldiers. The aim of this project is to provide a medical monitoring for the soldier at any time and any place and to design a soldier tracking system using GSM and GPS to provide wireless system for monitoring the parameters of soldier are as Body temperature & Blood pressure. A. System Architecture It is composed of two parts ) Soldier unit: This unit consists of two types of sensors such as temperature sensor, pulse rate sensor. These sensors are used to measure the signals from the human body such as heat signal, heart bit. After measurement, these analog signals are converted into digital signals and compared with the actual signals. If any discrepancy occurs between the measured signals and the actual signals, then it is considered as an emergency. The ARM 7 LPC8 processor plays an important role in controlling all the devices. It has an inbuilt A\D convertor. GSM transmitter is used to transmit the signals from the sensors which are controlled by the ARM7 microprocessor. GPS system is used to locate the position of the soldier. It is very helpful for the army station to rescue the soldier as soon as the emergency signal is received. The ARM7 family includes the ARM7TDMI, ARM7TDMI-S, ARM70T, and ARM7EJ-S processors. The ARM7TDMI core is the industry s most widely used -bit embedded RISC microprocessor solution. Optimized for cost and power-sensitive applications, the ARM7TDM solution provides the low power consumption, small size, and high performance needed in portable, embedded applications []. The ARM7TDMI-S core is the synthesizable version of the ARM7TDMI core, available in both VERILOG and VHDL, ready for compilation into processes supported by in-house or commercially available synthesis libraries. Optimized for flexibility and featuring an identical feature set to the hard macro cell, it improves time-to-market by reducing development time while allowing for increased design flexibility, and enabling >>98% fault coverage. The ARM70T hard macro cell contains the ARM7TDMI core, 8kb unified cache, and a Memory Management Unit (MMU) that allows the use of protected execution spaces and virtual memory. This macro cell is compatible with leading operating systems including Windows CE, Linux, palm OS, and SYMBIAN OS []. ) Army unit: Upon receiving the SMS, the VB s/w sorts the solder s location based on the GPS co-ordinates also the health status is displayed. In this way the army official s can keep a track of all their solders. Similarly, Army officer can also send reply to the corresponding soldier through VB screen in terms of SMS.

DESIGN DESCRIPTION All the design of proposed system are described in the following.the figure shows the basic circuit diagram of this proposed system. A. Hardware Description The heart of system is microcontroller which will access the data. In our project we will use ARM controller. To measure temperature of soldire there will be a temperature sensor. To convert the output of sensor into electrical form we will use signal conditioning (transducer). As controller operates only on digital data, so this analog data is to be converted into digital form by using ADC. But ADC is inbuilt in ARM processor. So the output of the signal conditioner circuit is directly connected to ARM processor. B. ARM 7- LPC 8 The ARM7EJ-S processor is a synthesizable core that provides all the benefits of the ARM7TDMI low power consumption, small size, and the thumb instruction. Operating systems such as Windows CE, Linux, palm OS and SYMBIAN OS. More than 0 real-time operating systems, Including qnx, Wind River s vx works. LPC8 Micro controller: Fig. Basic Circuit diagram of this proposed system GPS CONN V GPS TXD GPS RXD C. Temperature Sensor Lm The LM series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM thus has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling [8]. The LM does not require any external calibration or trimming to provide typical accuracies of ± C at room temperature and ± C over a full to +0 C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 μa from its supply, it has very low selfheating, less than 0. C in still air. The LM is rated to operate over a to +0 C temperature range, while the LMC is rated for a 0 to +0 C range [8]. 6

Heart Beat Sensor Heart beat sensor is designed to give digital output of heat beat when a finger is placed inside it. This digital output can be connected to ARM directly to measure the Beats per Minute (BPM) rate. It works on the principle of light modulation by blood flow through finger at each pulse. Fig. Heart Beat Cavity Measurement System send SMS content : coordinate send the message issue Crtl-Z char (0xA) <CR>: carrier return character (0x0D hex)[]. ICLM8is used for Heart Beat Sensor. Its dual low power operational amplifier consists of a super bright red LED and light detector. One will act as amplifiers and another will be used as comparator. LED needs to be super bright as the light must pass through finger and detected at other end. When heart pumps a pulse of blood through blood vessels, finger becomes slightly more opaque so less light reached at the detector. With each heart pulse detector signal varies this variation is converted to electrical pulse []. E.GPS Receiver: GPS Module The GPS smart receiver features the 6 channels.ultra low power GPS architecture. This complete enabled GPS receiver provides high position, velocity and time accuracy performances as well as high sensitivity and tracking capabilities. The hardware interfaces for GPS units are designed to meet NMEA requirements. The GPS receiver provides data in NMEA 08format with a Hz update rate. Generally message received by GPS is in NMEA [National Marine Electronics Association] message format and NMEA protocol which is most commonly used is NMEA08 protocol. GPS sentences beginning with the following specifications:$gpgga, $GPGSA, $GPGSV, $GPRMC, and $GPVTG. And sentences also begins with $GPMSS, $GPZDA as shown in [table ]. ) The Method of Tracking: The tracking method is based on the process of collecting continuously the coordinate (latitude, longitude) of mobile vehicle that could get from GPS receiver. After getting the coordinate, the mobile vehicle will send it to the supervised center via SMS or GPRS service. The supervised center will receive the coordinate of the mobile vehicle then displays on the screen. The mother board on the mobile vehicle is equipped a GSM modem- GM86 and it is directed by a bits microcontroller ARM Cortex M-LMS96. The microcontroller uses serial interface to communicate with GM86 by AT commands and send current position of the vehicle via SMS service by send the sequences commands below: ) Commands: AT+CMGF=<CR> AT+CMGS= <CR> Fig: GPS Receiver ) Specifications: 6-channels GPS search engine Ultra low power design (8mA, typical) Compact size Built-in low noise, high gain active antenna Super-cohesive magnetic for installation High sensitivity (up to -dbm typ) Apply to host devices with USB or RS ) Applications: Automotive Personal/Portable Navigation (PDA) Geographic Surveying Sports and Recreation ) Benefits to User: Ultra low power consumption Easy and fast to install Superior urban canyon performance Low cost with high performance F. GSM HARDWARE The core of data communication about this system lies in wireless communication control terminals that uses GSM Modules to transfer long-distance data extensively and reliably. It Support instructions of AT commands. SIM00 can be integrated with a wide range of applications. SIM00 is a Tri-band GSM/GPRS engine that works on frequencies EGSM 900 MHz, DCS 800 MHz and PCS900 MHz SIM00 provides GPRS multi-slot class 0 capabilities and support the GPRS coding schemes CS-, CS-, CS- and CS-. With a tiny configuration of 0mm x mm x.8 mm, SIM00 can fit almost all the space requirement in our application. Therefore, the MCU can connect with GSM modules very expediently through serial interfaces. Fig.. GSM module 7

SOFTWARE DESIGN This includes the coding of ARM 7 processor and coding for downloading of data and for GUI (Graphical User Interface) on server side. For ARM 7 :Embedded c using Keil software. For GUI :VB.Net VI. PARFORMANCE ANALYSIS A. Performance characteristics of system Range of communication is unlimited due to the use of GPS and GSM communication systems. As I am using GPS as guider, soldier can be secure to use appropriate guidelines. Using GSM SMS facility, it is not necessary to transmit any audio signals. These SMS are depending upon the present condition of soldier. As my system is monitoring parameters regarding with the help of soldiers, it is bit easy to provide a medical services as per requirements. It is possible to get a resolution less than 00 meters by using super software that being used by foreign countries. As stage pipelining used by ARM, execution speed of operation bit high. After each 60 seconds parameters regarding with the health of soldier will be send, so in time we can say a real time operating system. Sr. No B.
